Bit of an update for you.

I finished the insulated box for the 6" Typhoon fan.It works very well,just unfortunately not well enough.
Although the sound has been cut by better than 1/2 it is still just not quite enough to make my room sound proof from my neighbors.

As I have already popped my beans, I need to have lights . . . NOW!
So I have strung my Badboy T-5 under the shade for the HID bulb and am using it on 1/2 power for the new sprouts.

Since the T-5's produce so little heat compared to the HID light, I am using a vent booster fan to suck out the heat.The local Canadian Tire only had one in stock,but when I get another of these fans,the pair of them should provide enough airflow to handle the HID light.They are thermostatically controled and super quiet.

I will post some pics of the cabinet when I get the new fan system built and installed.

Here is a pic of the Vent fan.
